Lafayette residents rallied Wednesday morning near the site of last week’s fatal six-car crash in a collective cry for drivers to slow down.

The group of about 40, half of them children, carried signs that read “No more killings” and “This is our town; Let’s slow down” at the corner of Pleasant Hill and Springhill roads. A police speed trailer nearby tracked drivers’ speed in orange numbers.

“We see people zipping by in a hurry to get to work and we just want to help people stay aware that there are children here,” said resident Lynn Barr.

The rally was held after the speeding driver of a BMW slammed into the back of a Mazda on Stanley Boulevard at Pleasant Hill Road last week, causing a chain reaction with four other cars. The Mazda driver, 55-year-old Dale Zenor of Walnut Creek, died and five others were injured.

Frustrated residents want the speeding to end. Too many drivers travel above the speed limit and run red lights in a neighborhood that’s home to three schools, they said.
